INSTRUMENT FOR REMOVING WORMS FROM FOWLS THROATS.

SPECIFICATION forming part of Letters Patent No. 371,614, dated October 18, 1887.

Application filed June 22, I887. Serial No. 242,163.

To aZZ whom, it may concern.-

Be it known that I, NATHANIEL Mnrz, a citizen of the United States, residing at Lansdale, Montgomery county, Pennsylvania, have invented certain new and useful Improvements in Instruments for Removing Grape-forms from the Throats of Fowls, of which the following is a specification.

This invention relates to an instrument intended for removing the gape-worms from the throats of chickens and other fowls. Heretofore it has been customary to perform this delicate operation by means of a horse-hair looped or doubled upon itself and thrust down the throat of the chicken until the loop catches over the worm, when the horse-hair is removed, bringing with it the worm or worms. This operation is always attended with difficulty, and often with fatal results, as the fowl is frequently choked to death during the op eration. At the base of a chickens tongue there is a hard projection, which, unless great care is exercised in manipulating the horsehair, is liable to be caught thereby and torn off, carrying with it a greater or less portion of the tongue when the hair is removed. For these reasons I have devised a simple instrument, which consists, in general terms, of a guide adapted to be inserted into the throat of the fowl, which guide is provided with a groove or aperture, or grooves or apertures, adapted to receive and direct a filament, as a horse-hair, a piece of wire, or a thread, to the proper point in the throat of the fowl.

The most approved form of my device is that of a small tube having its lower endtapered and open, there being an eye formed in the wall of the tube near its lower end,through which one strand of the filament passes, leaving a portion of the guide Within the open loop as itprojects therefrom. The other details of the device will be hereinafter described more specifically.

In order that the invention may be better understood I have illustrated the approved form thereof in the drawings, in which Figure 1 is a side elevation of the implement. Fig. 2 is a longitudinal section. Fig. 3 is a face view of a different form of the instrument.

In the drawings, A designates the tube or (No model.)

guide, which is preferably of metal, or it may be made from hard rubber, celluloid, or other suitable material. Its lower end is tapered, as at a, and opposite said tapered portion the wall of the tube is perforated, as at a. The filament is represented by O, and preferably consists of a horse-hair, as that possesses the necessary elasticity, flexibility, and strength, although fine wire or thread might be used. In inserting the filament into the tube it is first passed lengthwise through the same,when the end extending through the tapered end is doubled upon itself and passed from the outside through the eye a into the tube and thence through the same to the upper end of the tube, where the two strands are united by a knot, as at c. This method of threading the filament insures that when the same is projected beyond the lower end thereof it shall assume the shape of an open loop, which, when inserted into the throat of the fowl, may be easily turned or twisted, thereby scraping the wall of the wind pipe, by which operation the worms are either caught between the strands of the filament, when they may be removed by quickly withdrawing the instrument, or they are disengaged from the windpipe, after which they may be coughed up by the fowl through the tube' or after it has been removed.

B represents a collar or bead surrounding the tube near its lower end, it being either in tegral with the tube or formed separate therefrom, as indicated in Fig. 2. This projection B serves as a stop to prevent the insertion of the tube too far into the throat of the fowl, and when formed separate from the tube may be adjusted thereon to suit the requirement of each individual case.

erator to twist the filament and thus tighten the loop on the object without irritating the throat of the fowl, the latter being protected by the tube. It also enables the operator to hold-down the tongue of the chicken, and when the tubular form of the invention is used it permits the fowl to breathe through the same,

2. The combination of a tube beveled at its end,-and perforated, as at a, and a filament passing through said tube, one strand passing through said perforation fromthe outside, 20 whereby it is maintained in an open loop, substantially as described. V

In testimony whereof I have signedmy name to this specification in the presence of two subscribing witnesses.
